JOHN W. COSGROVE, OF MEDFORD, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE i MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

MAOHINE.FOB SHAPING LIPPED SOLE-S.

Application filed November 29, 1924. Serial No. 752,988.

This invention relates to machines for operating upon lipped soles and is herein illustrated embodied in a machine of the type disclosed in Letters Patent No. 1,574,794, granted March 2, 1926, in. the name of the present inventor, for machines for shaping molding the feather at the toe of a reinforced insole of the Economy type. The illustrated machine, however, is also adapted to operate upon Gem insoles and upon various other types of lipped insoles such, for example, as leather insoles for Goodyear welt shoes and in various aspects the invention is not limited to embodiment in a machine of the-illustrative type.

In the use of the machine illustrated in the patent just referred to, the lip of the sole is shaped to the desired contour and the feather is pressed against a flat sole support so that, in the completed sole, the feather lies in the plane of the body of the sole. In many instances, however, after shaping the lip tothe desired predetermined contour at the toe in the machine above referred to, it has been found desirable to mold or breakdown the feather at the toe of the sole so that it will hug the last more closely and thus render it easier for the operator to last the toe and to maintain the lip in proper relation to the channel guide during the operation of sewing the upper to the insole.

In view of the foregoing, one object of the present invention is to provide a machine for shaping the lip and molding the feather of a sole which will be organized as to obviate the necessity of subjecting the sole to a further operation after the lip has been shaped for the purpose of molding or breaking-down the feather of the sole.

To this end, one feature of the invention consists in the provision, in a machine for operating upon lipped soles, of a form shaped to engage a substantial length of the lip and feather of a sole, and means con- 'structed and arranged to co-operate with said form to shape the lip and offset the feather. In working out this feature of the invention. as herein illustrated, co-operating inner and outer lip shaping forms, such as characterized the earlier machine above referred to, have been utilized, but the illustrative outer lip-engaging member is provided with a face inclined at the angle at which it is desired to offset the feather, and the sole support is provided with a plate or form having a beveled portion for co-operating with said face to offset or break-downthe feather. i

In the machine disclosed in the application above referred to, the lip is shaped between co-operating forms which have to be removed from the machine and replaced by co-operating forms of differentshapes when soles otditt'erent styles are to be operated upon. In practice a single run of soles may include soles of several dilferent styles and it is a further 0l)]6Cl3 of the presentinven-.

a the machine.

The invention further consists in the features of construction and the arrangements and combinations of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.

In the accompanying drawings,

Referring to the drawings, the machine therein shown comprises, in general, a head or frame 10; a work table 12 carried by the head 10 for supporting a sole while it is being operated upon; a feather molding block or form Lt carried by the work table for engaging the lower side of the feather oi" the sole; a form 16 for engaging the upper side of the leather and the outer side of the lip and for co-operating with the block H to mold or otl'set the leather; a form 18 tor engaging the inner side of the lip and cooperating with the form 16 to shape the lip;

vertically movable carriers or cylindrical slides 20 and 2:2 for the forms it; and 18 respectively; a slide 2-1: for imparting rearward movement to the carrier 2:! and the form 18; a horizontal main shaft 26; and mechanism including the cam disk 18 on the main shaft tor actuating the carriers :20 and 22 and the slide 2%.

Except as hereinafter described, the frame 10, the slides 20, 22 and 2- the means for supporting and guiding these slides and the mechanism for actuating them are substantially the same in construction as corresponding parts described in the application above referred to and the same movements are imparted to the slides and to the forms 16 and 18 as in the machine of said patent. Consequently, it will be unnecessary to describe the construction or mounting of the slides or carriers or the operating mechanism therefor herein, reference being had to said application if desired tor a detailed description thereof and of other parts not fully described herein.

Referring more particularly to Fig. l, the work table 12 ot the illustrative machine is secured to a forwardl projecting portion of the head or frame 10 b v means of screws such as that shown at 30, and is provided with two vertical dowel pins 232. 32 arranged to enter apertures 34, 34- in thc feather molding block 14- dclachahl to secure the plate to the work table and accurately to locate the plate relatively to the forms it; and 18.

The feather molding hlocl; or form 14 is of the general triangular shape best shown in Fig. 3, the plate being formed with converging edge faces 36, 36 meeting at a point at the rear extremita oi the plate and adapted to conform to the contour of the lip at the toe of a sole. The converging edge faces "from the slide or carrier 20.

36, 30 are also beveled or inclined transversely at the angle relatively to the plane of the wort; table at which it is dcsircd to bend the feather. As shown, the third edge face of the block it is also beveled, as at 38, to l'acilitate the placing of a sole in position to be operated upon by the block it and the forms lb and it). liotches at), 4-0 are formed in the beveled edge face 35 adjacent to the bottom of the block to receive a screw driver or like tool which may he used to lift the block or form 14 from the dowel pins 32, 32 when it is desired to remove thc block. By locating the holchcs 40, it) at opposite sides ot a line extending through the apcrturcs 34, List as shown, thc screw driver or other tool may be used most cllcctivclv lo pr v the block or form 1-! from the dowcl pins. As shown in the dravv'ings, relatively sharp corners are tin-med at thc junctions ol' the bcvclcd cdge l'accs with the llat upper face thereof, this construction causing a sharp lin ol demarcation to be formed upon the lower l'acc ol :1 .-olc opcratcd upon thcrcby between the molded leather and the body of the sole. Such a sharp line ol denial-ca tion may be avoidcd il' dcsircd b v roundint thc corners ol the cdgc larcs ol the upper face ol' the block or form H.

The form us. as iu-rcinla-l'orc mentioned. is adapted to co-opcrate wilh thc bloclt H to mold thc lcathcr, and to coopcratc with the form lti to shape thc lip. 'l'o adapt it for these purposes the form ll providcd with a central V-shapcd notch l2 providing opposite walls tor engaging the l'cathcr and the lip at opposite sidcs of thc toc. The lowcr portions of the walls l'ormed by the notch "l2 arc inclincd transvcrscl as shown at iii: in planes parallel to thc bcvclcd laces ill. 34 ol the block l-l. thus providing molding 'l'accs complcmcntal to the molding faces ol tlu; block llconstructed and arrangcd to coopcratc with thc lattcr to mold or brealt down the leather. Above thc bcvclcd lower portions ol the opposite walls ol the notch 42 said walls are inclincd more sharply to the perpcndicular. as indicatcd at 40. thus l'orming bcvclcd l'accs which are inclined at too angle which it is desired to scl the lip of the sole. To enable thc torm ll; to be scoured to its carricr the lorm is provided with an npstandii'ig lug -13 which is llolt'llcd at to receive a screw 5:! projm-ting torwardly The screw is provided with a head arranged to overlap the front face of the lug 43. a smooth shank portion for ent ring the notch 50 and a rcduccd shank portion which is threaded into the carrier 20. in attaching the Form 16 to the carrier Q0 the form is moved horizontally cdgewise in a direction to engage the notch 50 with the smooth shank port ion of the screw and insert the log 48 bctwccn the front Ill) face'of the carrier 20 and the head of the screw 52. A horizontal rib 54 (Fig. 1) eX- tends transversely across the front of the carrier 20 and is arranged to inter-engage with a horizontal groove of corresponding width in the rear face of the'lug' 48 to prevent twisting of the form 16 and insure that it will be maintained in a horizontal position "it'h its feather and lip engaging faces parallel to the respective. faces of the plate 1% and the form 1.8. The edgewise sliding movement of the plate 16 in the operation of attaching it to the carrier 20 is limited by means of a stationary bearing surface 56 Fig. l), hereinafter referred to, which ser es accurately to locate the form 16 in proper vertical alinement with the plate 14 as well as to prevent thecylimlrical carrier '20 from turning in its guideway. A latch 58 is pivoted at 60 to one side of a fixed guideway 61. in which the carrier 20 reciprocates and this latch is adaptedto swing under the intluenceof grav into a position (1 termined by a stop screw 62 to co-operate with the bearing surface 56 to position the form 16 relatively to the carrier 20 and the plate 1-l and detachably to hold said form in operative position. The head of the stop screw (:52 overlaps the lower extremity of the latch 58 to hold the latch firmly against side thrust. The latch 58 may be swung by means of a handle 64 in a direction to free the lug to permit convenient removal of the forth 16. In this way the form 16 may he easily and quickly detached from its carrier without the necessity of loosening a nut, screw or like part. After the form 16 has been inserted in position upon the carrier 20 it may be held in place merely by allowing the pivotet latch 58 to swing into the operative position in which it appears in Fig. 3, thus avoiding the necessity of tighteningclamp device or the like.

The form 18 is arranged to cooperate with the form 16 to shape the/lip of a sole to a desired predetermined contour. To this end the form 18, as best shown. in 2, is provided with a rearwardly projecting, V- shaped portion adapted to engage the inner side of the lip and to cooperate with the upper faces 46 formed at opposite sides of the Vehaped notch 42 in the form 16 to shape tl e lip. For this purpose the converging edge faces of the V-shaped portion of the form 18 are inclined transversely at an a -e corresponding tothe angle of. bevel of the faces -16 of the plate 16, thus providinc; lip sh aping faces upon the form 18 which are complemental to the faces 41) of the form 16. The cooperation of the faces. 46 with the complemental faces upon the form 18 insures that the lip of the sole will be inclined inwardl from a plane normal to the face of the sole. To insure that the inner form will engage the stock at the base ofthe lip, the

under side of the form 18 is somewhat undercut or beveled, as indicated at 66. This construction insures that the edge of the form 18 will seat itself in any groove or channel which may be formed in cutting an inner channel flap in the process of forming a compound lip upon asole and will facilitate the final operation of setting the lip by localizing the setting pressure exactly at the base of the lip.

In order that the form 18 may be readily removed from the carrier 22 so that it may be replaced by another form having a different contour the form 18 is provided with a transverse, dove-tailed tongue 68 which is received in a correspondingly shaped groove 70 in the lower portion of the carrier 22. To enable the form 18 to be quickly removed or inserted novel means is provided for locking the tongue 68 in the groove 70. This means comprises a horizontal lock bolt 72 which is slidably mounted in the carrier 22 above the groove 70, the bolt 72 extending transversely of the groove. At its rear eX- tremity the lock bolt 72 is provided with a depending wing 74 adapted to enter a notch 76 (Fig. 2) in the rear side of the tongue 68 positively to locate the form 18 horizontally with respect to the form 16 and the plate 1% and securely to lock the form in place. The lock bolt 72 projects forwardly beyond the carrier and provided with a head 7 8 by which it may be manipulated for the purpose of disengaging the wing 74 from the notch 76. Normally, the wing 74 is yield ingly held in engagement with the notch 76 by means of a spring 80 which encircles the lock bolt 72 between the head 78 and the front face of the carrier 22. By pressing rearwardly upon the head T8 the wing 74 may be forced backwardly'to disengage it from the notch 7 6, thus freeing the tongue 68 so that the form 18 may be readily disen- {raged fromits carrier. As shown in Fig. 2, the rear edge face of the dove-tailed tongue 68 is curved at one side of the form 18, as clearly shown at 82 in Fig. 2. In the operation of slidably inter-engaging the tongue (58 with the groove 70 the curved portion 82 of the tongue first engages the wing 74 of the lock bolt and acts; as a cam to slide the lock bolt rearwardly against the force of the spring 80, thus enabling the form 18 conveniently to be attached to the carrier 22 without the necessity of manually releasing the lock bolt.

The forms 16 and 18 are normally positioned in the samerelation to each other and to the work table as are the corresponding forms disclosed in the patent hereinbefore referred to. As in the case of the outer form in the machine of said patent, the form 16 of i the illustrated machine is normally positioned at a suiiicient elevation above the work table to permit the insertion between the form and the Work table of the feather at the toe of the insole whileat the same time the form 16 is near enough to the Work table to enable the faces 46 at the opposite sides of the notch 42 to be engaged by the lip of the insole as the latter is pushed rearwardly across the work table and block It by the operator. The form It thus serves as a gage to position the insole longitudinally with respect to the work table for the perl'ormance oi the lip setting and feather molding; operations. thus renderingit' unnect sary to provide special gages or other positioning devices for thi. purpose. The form 18 is normally positioned omewhat higher above the work table than the form It to facilitate the presentation ol the insole to the latter.

To assist in :hapine or molding the lip and the feather it: is desirable to have the shaping or molding instrumentalities heated. in the illustrated machine heat is supplied to the forms it; and 18 by means of two stationarily mounted electric heating units at and 88. l't ])(tfil\(fl V (Fin. al is shown. the unit tit; is in the torm ot' a cylindrical block which i= located in a soeketed member tit) (see Fig. :3) r'eeured to the exterior of the guideway til. the member tit) having l'ornied thereon the hearine surface at; hereinbe'lore referred to which. in addition to locating the form it} and preventing the carrier 2t) from turnina provides also a contact tare across which the vertical edge of the hip; i rubs as the l'orni ltl raised and lowered so that heat will be continuously conducted from the unit Pitt to the form lti. The heatin; unit he also consists of a cylindrical block which is received in a sot-li'eted member 92 carried by a lined bracket (H- in which the carrier Z-l it mounted to slide. A smooth 'l'ace Sit formed upon the member 92 at one side of the unit tits, engages the adjacent side of the slide it to insure continuous conduction oi heat from the unit; through the slide 2- and the carrier to the form 13.

The movements imparted to the forms it) and 18 are substantially the same as the movements imparted to the corresponding: forms in the patent referred to. llriel'ly described. the operative movements of these forms are as followsz--Atter the insole has been positioned on the work table by the en- ;iag'ement ot the lip with the ares-1t; of the form lti. both the form "it; and are depressed until they are brought into pressing: engagement with the insole. the form it on getting the feather ol' the insole adjacent to the point of the toe and the outer side oi the leather. and the form 8 engaging the upper face of the insole between the converging toe portions oi the lip. In the illu-trated machine. however. on account of the angle ol the t-olnpleniental beveled faces ll; and 34- on the form 16 and block 14. respectively, the feather is offset or broken down by the cooperation of the form 16 with the block 14 substantially as shown at 84 in Fig. 7. The form 16 is held against the feather under comparatively heavy pressure positively to break down the feather, whereas the form 18 is initially held in engagement with the upper face of the sole under comparatively light pressure. After the forms lo and 18 have been depressed into engagement with the insole the form 18 is moved horizontally toward the form It; to mold or shape the lip into the retpiiredeoir tour. 'lhereafter additional pressure is applied to the form 18 to force the marginal portion of the beveled lower side of said form firmly against; the channeled portion of the insole at the base of the lip. this additional pressure causing the marginal portion of the form to apply heavy downward pressure exactly at the base of the lip. This operation assists in setting the lip so that it will retain its molded contour. It will be reel by reference to Fig. 1 that when the linal or lip-setting pressure is applied to the form 18 through the action of its actuating cam in the disk 28. not only will the leather continue to receive pressure from the form it but the pro-sure applied through the latter i'orin will actually be increased,

From the foregoing it will be apparent that the leather will be molded or broken down at the toe of the insole and that the portion of the lip adjacent to the toe will be molded or shaped to a pretletermined eontour at what is practically a single operatit'in. The use of the illustrated machine obviates the necessity oi performing an additional operation upon the insole for the purpose. of oti'settine the leather alter the lip has been molded and set, and thus an additional han- (lliltif oi the insole and a consideralne amount; of time is saved in the mcumlaeture of the insole.

As hereinbel'ore mentioned, forms of difl'erent shapes will be employed for insoles having dillerently shaped toe; and accordingly provision has been made. whereby the 'ftl'lllt; may be removed and replaced in a minimum amount of time and with a minimum amount. ol eli'ort on the part of the operator. Each of the molding members may be secured in place in the machine by substantially a single mmen'u-nt; and they are automatically positioned in accurate workin; relation to one another and etl'et-tively Ftt'llt'ttl in place by the (plick-dt'taehable connections hereinbetore describet'l.

In case it should be desirable at any time to shape and set the lip o'l an insole without othettiug or breaking down the feather this result. may be accomplished with the use of the illustrated machine by replacing the feather molding block 1-t by a llat'v plate adapted to cover the entire surface oi the work table, as indicated by dotted lines at;

98 in Fig. 1, and by Substituting for the form 16 a corresponding form having a feathereugaging face which is parallel to the plate 98. p
